1 Features 3 Description

The TPS736xx family of low-dropout (LDO) linear

1• Stable with No Output Capacitor or Any Value or

voltage regulators uses a new topology: an NMOS Type of Capacitor

pass element in a voltage-follower configuration. This

• Input Voltage Range of 1.7 V to 5.5 V topology is stable using output capacitors with low

• Ultra-Low Dropout Voltage: 75 mV typ ESR, and even allows operation without a capacitor.

• Excellent Load Transient Response—with or It also provides high reverse blockage (low reverse

without Optional Output Capacitor current) and ground pin current that is nearly constant

over all values of output current.

• New NMOS Topology Delivers Low Reverse

Leakage Current The TPS736xx uses an advanced BiCMOS process

to yield high precision while delivering very low • Low Noise: 30 μVRMS typ (10 Hz to 100 kHz) dropout voltages and low ground pin current. Current

• 0.5% Initial Accuracy consumption, when not enabled, is under 1 μA and

• 1% Overall Accuracy Over Line, Load, and ideal for portable applications. The extremely low

Temperature output noise (30 μVRMS with 0.1-μF CNR) is ideal for

powering VCOs. These devices are protected by • Less Than 1 μA max IQ in Shutdown Mode thermal shutdown and foldback current limit.
